Rose is a highly significant ornamental plant with substantial edible and medicinal value,cultivated worldwide primarily for perfume production.Recently,Rosa yangii,a new species found in northwestern Yunnan,China,has drawn attention due to its strong sweet scented flowers.In this study,the floral components of R.yangii were extracted at different flowering stages using solid phase micro extraction(SPME)and analyzed through gas chromatography-mass spectrometry(GC-MS).A total of 131 volatile organic compounds(VOCs)were detected from R.yangii,including 69 odor compounds.The production and release of floral VOCs were the highest during the initial-open stage,making it the most suitable time for harvesting as a significant number of floral components were synthesized and preserved.The analysis of the odor activity values(OAV)highlighted several key aromatic ingredients of R.yangii,such as eugenol,methyleugenol,benzeneacetaldehyde and phenylethylalcohol,heptanal,decanal,(E)-2-hexen-1-yl acetate,caryophyllene,and others.Metabolome and time-order gene co-expression networks(TO-GCN)revealed that VOCs and benzenoids/phenylpropanoids,along with associated genes,played a pivotal role in the overall floral regulatory network of R.yangii.MYB and bHLH were identified as the essential regulatory factors governing the regulation of eugenol synthase(EGS)and isoeugenol synthase(IGS),consequently influencing the sweet scent of R.yangii.The findings of this study provide a scientific foundation for enhancing fragrance through molecular breeding of ornamental plants.Furthermore,the study facilitated the development and utilization of this new plant’s essential oil material in various industries,including food storage,aromatherapy,cosmetic,and perfumery. 展开更多

Silica aerogel with different hydrophilicities were prepared from tetramethoxysilane,Methymethoxysilane,tetramethoxysilane-propyltrimethoxysilane,or tetramethoxysilane-phenyltrimethoxysilane mixtures via supercritical drying process(labelled as TMOS-AG Me-TMOS-AG,Pr-TMOS-AG,or Ph-TMOS-AG,respectively).Three fragrances,including geraniol,ethyl vanillin,and menthol,were loaded to TMOS-AG.The thermal analysis confirmed all loading fragrances are stable until over 200℃.And among all fragrances,geraniol presented the maximum loading contents(L_(m)).Concentration dependences indicated the geraniol was mono layer absorbed.Py-GC/MS of geraniol in TMOS-AG under both N_(2)and mimic air atmosphere(90%N_(2)and 10%O_(2))confirmed that loaded geraniol could be thermally controlled-released beginning at 200℃.As N_(2)absorption confirmed,even absorption/desorption equilibrium constant(k)was determined mainly by hydrophilicity of silica aerogels,and the maximum loading contents(L_(m))were influenced more by the pore size.Due to mono layered absorption,bigger pores usually give less specific areas and less absorbing sites for geraniol,and then present lower L_(m). 展开更多

A general and versatile strategy to prepare melamine-formaldehyde(MF)microcapsules encapsulating oil-based fragrances by combining solvent evaporation and in situ polymerization was proposed in this work.The oil-based fragrance was pre-encapsulated by an inner polyacrylate membrane via solvent evaporation,followed by in situ polymerization of MF precondensates as an outer shell.The polyacrylate membrane is used as an intermediate bridging layer to stabilize the oil-based fragrance,and to provide driving forces for in situ polymerization of MF precondensates through electrostatic attractions between carboxyl groups and ammonium ions.It was demonstrated that MF microcapsules containing clove oil were prepared successfully.The amount and the composition of the intermediate polyacrylate bridging layer were critical.Smooth and sphere-shaped MF-clove oil microcapsules were prepared when the weight ratio of polyacrylate to clove oil was over 60 wt%and the concentration of acrylic acid(AA)increased to 10 wt%in polyacrylate.In addition,MF microcapsules containing sunflower oil and hexyl salicylate were prepared by using this method.The work suggests that this new approach can be potentially used to encapsulate various core materials,tuning the shell properties of microcapsules such as thickness,mechanical strength and release properties. 展开更多

The objective of our study was to lay a foundation for the effect of flower flagrance on human emotions and to provide a theory for the choice of indoor plants and the improvement of the olfactory environment. Specifically, our purpose was to study human physiological responses to flower fragrance of Lilium 'Siberia' and Rosa 'Escimo'. The participants were 31 college students. Blood pressure, pulse rate, finger temperature (FT) and galvanic skin response (GSR) were measured. The results show that the fragrance of Rosa 'Escimo' causes the diastolic pressure and pulse rate of the participants to reduce significantly. The average decrease was 0.37 kPa and 2.23 beats per minute, which indicates that sympathetic nervous activity increases, physiological arousal decreases and emotional alleviation occurs. Furthermore, the GSR of participants significantly increased by smelling the fragrance of Lilium 'Siberia', indicating that both sympathetic nervous activity and physiological arousal increased. But the data could not prove that flower fragrance stimulation has an effect on changes in systolic pressure and finger temperature. Some other factors, such as basic emotion and weather, may have an effect. 展开更多

This study was conducted to evaluate the antimierobial activity of ethylparaben (ethyl para-hydroxybenzoate) in flavoring agents and fragrances used tot cigarette production. In brief, different levels of ethylparaben were added to Ziyun and Ruanzhen fragrance concentrates, and fermented with or without the additiorl of extra microbial strains. The aroma components in the fermented samples were detected via gas chromatography-mass spectrometry (GC/MS) assay. The results showed that ethylparaben had good antimicrobial activity on the microorganism in Ziyun and Ruanzhen fragrances, and as it significantly inhibited the growth of Sac- charomyces sp. Aeetobacter sp. , Agrobacterium sp. and Bacillus sp. , with an inhibition rate of 53%. Under natural fermentation condition, 91. 885% of the micro- organisms were inhibited by adding 0. 1 g/kg ethylparaben, 97.69% were inhibited by adding 0.3 g/kg ethylparaben, and 100% were inhibited by adding 0.5 g/kg ethylparaben. Moreover, the addition of ethylparaben had no obvious influence on the aroma components of the favoring agents and fragrances. So, it carl be used as a preservative for the quality control of favoring agents and fragrances for cigarette production. 展开更多

The luxury market has experienced considerable growth over recent years, being one of the sectors that have been the most resistant to the current economic recession. Selective fragrances make up one of the primary categories of the so-called accessible luxury consumed by a middle class that is seeking to approach the upper classes by copying their lifestyle. Despite the importance of this market, there is relatively little literature existing in regards to the study of the image of luxury brands due to the complexity of the luxury phenomenon. This article presents the results of an initial qualitative study conducted on focus groups of luxury fragrance consumers, making it possible to identify the types of attributes to be considered when studying the brand image of said luxury products. Subsequently, a quantitative study was conducted in order to determine the perceived image of the principle luxury fragrance brands by consumers. Thanks to this study, it has been possible to determine the typical profile of each of the analyzed brands so that a subsequent comparison may be made with the advertising created by said brands in order to verify whether or not the image projected in their advertising corresponds with the perceived image of their target audience. 展开更多

Jasminum sambac(jasmine flower),a world-renowned plant appreciated for its exceptional flower fragrance,is of cultural and economic importance.However,the genetic basis of its fragrance is largely unknown.Here,we present the first de novo genome assembly of J.sambac with 550.12 Mb(scaffold N50=40.10 Mb)assembled into 13 pseudochromosomes.Terpene synthase(TPS)genes associated with flower fragrance are considerably amplified in the form of gene clusters through tandem duplications in the genome.Gene clusters within the salicylic acid/benzoic acid/theobromine(SABATH)and benzylalcohol O-acetyltransferase/anthocyanin O-hydroxycinnamoyltransferases/anthranilate N-hydroxycinnamoyl/benzoyltransferase/deacetylvindoline 4-O-acetyltransferase(BAHD)superfamilies were identified to be related to the biosynthesis of phenylpropanoid/benzenoid compounds.Several key genes involved in jasmonate biosynthesis were duplicated,causing an increase in copy numbers.In addition,multi-omics analyses identified various aromatic compounds and many genes involved in fragrance biosynthesis pathways.Furthermore,the roles of JsTPS3 in b-ocimene biosynthesis,as well as JsAOC1 and JsAOS in jasmonic acid biosynthesis,were functionally validated.The genome assembled in this study for J.sambac offers a basic genetic resource for studying floral scent and jasmonate biosynthesis,and provides a foundation for functional genomic research and variety improvements in Jasminum. 展开更多

Controllable profragrance nanoparticles are in great demand for long-lasting scent in flavor and fragrance industries.However,the practical applications of controllable fragrance release are limited by the non-tunable size,structural heterogeneity and poor reproducibility.Herein,a coumarin-derived phototrigger(CM-OH)is covalently conjugated with alcohol fragrances to obtain the corresponding profragrances(CM-R)which enable to release fragrances under the light controlling conditions.Furthermore,we introduce a new engineering strategy to construct fine tunable and highly uniform profragrance nanoparticles with flash nanoprecipitation(FNP)technology,which features commercial available amphiphilic pluronic F127 polymers by encapsulation of photoactivatable profragrances CM-R in hydrophobic cores to enhance the long-lasting photo-controllable fragrance release.With the assistance of FNP technology,amphiphilic pluronic polymer and profragrances CM-R in organic solution are instantaneously mixed and subsequently precipitated in the multi-inlet vortex mixer(MIVM),thus obtaining the pluronic F127-encapsulated profragrance nanoparticles with good homogeneity.Compared to the traditional thermodynamic encapsulation method,the novel kinetic FNP technology can not only tune the size of profragrance nanoparticles with narrow distribution,but also distinctly improve the batch-to-batch reproducibility,which affords an alternative method for scale-up preparation of amphiphilic profragrance nanoparticles in precisely controllable fragrance delivery system. 展开更多

Controlling the size of fragranee microcapsules using designed agitator paddles was investigated and studied by CFD simulation. First, different fluid flows were established by varying stirring speeds, reactor scales, and agitator paddle design, and the effects of each on particle size and distribution of prepared microcapsules were determined. The experimental results showed that the pattern design of orifices in the plate paddles control the flow field well. Narrow particle-size distributio ns of the microcapsules were obtained. The fluid flow characteristics including fluid velocity field, turbulent kinetic energy field, and shear stress distribution for thedifferent agitator paddle types in different reaction kettles were simulated using CFD tech no logy. The correlations between simulated data and experime ntal results were an alyzed. Significantly, the simulated average flow velocity was found to show good negative linear correlation w让h the average particle size of prepared microcapsules, with a correlation of y =-2.166x + 42.626. 展开更多
